<P>PROBLEM TO BE SOLVED: To provide an imaging device capable of reducing noise. <P>SOLUTION: An imaging device 100 comprises a storage unit 160 and a noise reduction processing unit 250. When the ratio of an electrical signal SS1 outputted from a microphone 230 when an imaging unit is determined to be in operation by a determination unit 251 to an electrical signal SS1 outputted from the microphone 230 when the imaging unit is not determined to be in operation is not smaller than a threshold, the storage unit 160 stores the electrical signal SS1, outputted from the microphone 230 when the imaging part is determined to be in operation, as a noise signal. By use of the noise signal stored in the storage unit 160, the noise reduction processing unit 250 reduces the noise in the electrical signal SS1 outputted from the microphone 230. <P>COPYRIGHT: (C)2012,JPO&INPIT |
